Title: CONTROL UNIT FOR CONTROLLING A STARTING PROCESS OF A DRIVE UNIT IN A MOTOR VEHICLE
Abstract:
The invention relates to a control unit for controlling a starting process of a drive unit in a motor vehicle, wherein upon a starting demand, the control unit outputs a starting signal for implementing corresponding starting measures for starting the drive unit, and wherein upon the starting demand and/or upon the outputting of the starting signal and/or after successful starting of the drive unit, the control unit transmits to a memory unit a memory signal, which is dependent on or independent of the type of starting process, for storing at least one memory entry, and the memory unit thereupon performs a memory entry, which is dependent on or independent of the type of starting process, in such a way that it increases by one the value of a counter unit provided for the memory entry. The invention is characterized in that, when a predefined counter limit value is reached or exceeded by the value of the counter unit, the control unit no longer permits a predefined type of starting process and/or a predefined type of shut-down process of the drive unit.
